Quantification of High-dimensional Non-Gaussianities and Its Implication to Fisher Analysis in Cosmology

Quantification of High-dimensional Non-Gaussianities and Its Implication to Fisher Analysis in Cosmology

It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been proposed to extract information from non-Gaussian cosmological fields that perform better than the power spectrum. The F...
